If you’ve ever wanted to apply for US citizenship, you’ll need to know how to fill out Form N-400. This form is used to request US citizenship for people who are lawful permanent residents of the United States. There are currently approximately 8.8 million people who can apply for naturalization. While it’s not easy to naturalize, it is possible to do so by following a few simple steps. Before you fill out Form N400 application, you should first determine whether you need to seek legal assistance. If so, speaking with an immigration lawyer is a good idea. There are also organizations that offer free legal assistance, such as CitizenshipWorks. There are also many different ways to submit your application, including online or by mail. In either case, you will want to make sure you type in all of the questions and answer them correctly. You can also print out the form to fill it out later. When you’ve decided to submit your application for naturalization, the next step is to pay the filing fees. If you qualify for a fee reduction or waiver, you will be able to get the fee waived, so you can skip the cost of filing. You must also visit a USCIS field office to have your fingerprints taken. You can do this online or in person at the USCIS office in your area. When filling out Form N-400, it’s important to ensure that all of the information on the form is correct. If there is an error, the USCIS may reject your application. If you’re unsure about any of the information on the form, consider consulting an immigration attorney to provide you with clear instructions. If you have been a permanent resident of the US for at least three years, you can apply for naturalization by filing Form N-400. However, you must be sure to wait until you’ve lived in the country for three years before filing. Otherwise, you may have to wait another five years to be eligible for naturalization. You can find information on Form N-400 on USCIS’s website. Obtaining the form online is free, but there are still some costs involved. Generally, you’ll have to pay a processing fee of $640, and an additional biometrics fee of $85. You can also download the form and mail it out yourself. When filling out Form N-400, you should not leave any space blank. The USCIS will scan your answers, so a mistake on the question could delay the processing of your application. Additionally, USCIS officers may want to check for extra marks or information that will cause them to reject your application. These extra marks and information can also delay the processing process. If your parents are U.S. citizens, you may not need to file Form N-400. Rather, you should file Form N-600 instead. This certificate will prove that you are a U.S. citizen and that you are the child of U.S. citizens. If you were born in another country, you need a citizenship certificate in order to prove your citizenship status.
